PORATION OF MINNESOTA.

Application filed May 31,

To @ZZ whom t may concern.

Be it known that I, CLAUD J. Cnnrroiv, a citizen of the United States, resident of Cwatonna, county ofSteele, State of Minneand quickly ldetached from `the stove for cleaningl or other purposes.

' A further object is to provide a burner of improved construction in which provision is made for spreading and distributing the gas flowing` through the burner and preventing backdire or popping of the gas in the burner.

Other objects of the invention will appear from the following detailed description.

InA the accompanying drawings forming part of this specification, Figure 1 is a plan view of a stove and burner embodying my invention,

Figure 2 is a sectional view on the line 2-2 of Figure 1,

Figure 3 is a sectional view on the line 3`3 of Figure l,

Figure 4 is a detail view of the upper portion of the burner,

igure 5 is 'a view burner, showing the gas spreading-or distributing device therein,

Figure 6 is a detail view of a portion of this distributing device.

ln the drawing, 2 represents the frame of the stove. I have shown the stove equipped with two burners but obviously any desired number may b-e employed. 3 is a pipe having a coupling i at one end for connection with a hose leading to the source of gas supply. Brackets 5 support this pipe on the frame of the stove burner. Regulating valves 6 having operating handles 7 are mounted in the pipe 3 and project inwardly therefrom. Each burner comprises a base 7, preferably substantially circular in form, having an annular gas chamber 8 therein. An arm 9 projects from this base on one side and has a passage 10 therein communicating with the chamber 8 and leading to the fiar* ing end portion 11 of said arm, said end portion having a wall 12 provided with air intake openings 13 and a socket la for a gas nozzle 15 which communicates with the of a portion of the popping in the mixing chamber.

the ports 13. rlhe arm is not secured to thel nozzle 15 but merely'has ka close tting joint therewith and may be readily removed without the use of tools.

The opposite side of the base jecting iiange 16 that is adapted to rest on a shelf 17 carried by a depending'bracket 18 and the flange 16 has a seat 19 therein for a clamping screw 20 that is mounted in the bracket` 18 and is adapted to bemoved into engagement with the flange 16 for clamping the burner solidly in thejframe between the bracket 13 and the nozzle 15. screw 20 is' loosened, and retracted, the

burner may be lifted entirely clear vofthe stove frame without the use of wrenches,v

screw drivers or other means, the screw 20 having a llinger grip on one endfand being easily operable with thefingers for loosening s or Ytightening .the burner.

A cap 21 is provided for the burner base, secured thereon by suitable means, such as a screw 22, said cap having an annular portion 23 provided with points 24 and perforations 25 therein. l/Vithin this annular portion 23 isa coil 26 of comparatively thin sheet metal, the convolutions having little projections or teats 27 pressedthereinin staggered relation, will be separated from one another by vnarrow annular spaces, through which spaces the gas will iiow from the chamber 8 to the exits of the burner. I have found that this narrow band withl they annular gaps between the convolutions will have the efect of spreading and separating the gas, compelling it to iiow evenly and uniformly and :f )reventing` popping or. backiriiig in the burner. The band is of suihcient depth so ythat the gas flowing' therethrough can not pop back might do plate. i

I have determined by actual experiment that the band coiled in this way is very effective as a spreading means for the gas and as a means for preventing back-firing and in the case of a thin perforated this band may be had at any time y upon the removal of the screw 22 at which time the 7 has a pro-A l/V hen thel into the chamber beneath, as itv so that the convolutions f ico other, 'fitting within upper section or annular portion 23 can be easilj.7 separated from the base portion. Access may then be conveniently had to the mixing,` chamber and the passage l0.

l claim as my invention:

l. A gas burner comprising a mixing chamber therein, an upper portion having, perforations for the passage of the gas, and a spreading device comprisinga flat band Ytermed into a series olt convolutions having` continuous annular spaces between the convolutions fitting within said burner above said base and means for separating,` the convolutions or said band.

O 't gas burner comprising` a base having?` I. .IA a mining` chamber, a cap seated. on said base a base having l and provided with an annular portion havseries or pertorations in its upper a gas spreading device inounte within saitL annular portion above said base and comprising a flat metallic band rolled to forni a series of convolutions, one within the other, said band having projections or teats pressed therefrom tor separating the convolutions one `troni the other and provithng` narrow annular passages between 'them tlrr ugh which the gas is compelled to pass to reach said periporations.

3. A ygas burner comprising a suitable base having a chamber therein and a band ot comparativelg7 thin material rolled to torni a series of eonvolutions, one within the said chamber, said band having means on its surface Jrior separating the adjacent convolutions, one from the other, to provide narrow annular passages ing a wall and Asaid base,

between them, whereby the acetylene gas will be broken up and `mixed in its passage through the burner.

l. The combination, with a stove frame and gas supply pipe and gas'nozzle therefor, ont burner base having a hollow arm on one side provided with air intake openings and socket to receive said gas nozzle, a bracket supported on saidstove 'trame opposite said nozzle, said burner base having an arm seated on said bracket and a thumb screw mounted in said bracket and having its end positioned to eontact with said arm for Jr'orcing' said burner lese and said hollow arm toward said nozzle.

5. .er gas burner comprising a base having a hollow arin leading` thereto and an annular passage in the lower part of said base, a cap fitting on said. base and having perforations ink the top thereof, and an annular passage conununicatino,` with the passage i means fitting within the annular passage in said cap "for spreading the gas in its passage to said perforations, and said spreading means consisting of a thin band rolled to :torrn` a series of convolutions, one within the other, and means for separating the convolutions of said band to provide narrow annular passages through which the gas iiiows to said perrorations, said annular passages being` continuous and substantially uniform.

ln witness whereof, have hereunto set my hand this 25 day o't May' 1921.

CLAUD J. CLEFTON.
